Audio-Technica's Freeway 220 Series Wireless System provides proven performance for artists and presenters in a variety of settings. The heart of this rugged True Diversity VHF system is the ATW-R220 receiver, which comprises two independent receiver sections in a single housing. True Diversity operation selects the better signal from the 2 receiver sections, reducing dropouts and interference while increasing system reliability. Other professional features include balanced and unbalanced outputs, ground lift, adjustable squelch and two detachable antennas. The ATW-T202 handheld microphone/transmitter features a unidirectional dynamic element for feedback rejection and dependable performance, as well as a battery-condition indicator and adjustable gain control.
